Industry Expert Validates Unprecedented Effectiveness in Removing Contaminants From Water

SANTA ANA, CA--(Marketwired - Sep 29, 2014) - BioLargo, Inc. (OTCQB: BLGO) announced that scientists at the University of Alberta Department of Agricultural, Food and Nutritional Science tested and validated its Advanced Oxidation System (AOS) Filter for use in food and agriculture. This work follows on the heels of validation work by the University of Alberta's Department of Engineering for its use in eliminating soluble organic contaminants like those found in oil sands tailings ponds.

The tests validated unprecedented effectiveness in destroying highly concentrated contaminants in sample water, including Listeria and Salmonella. Although the testing is applicable in many areas, food safety was a primary concern of this most recent work. Professor Lynn McMullen evaluated the results and commented, "The AOS Filter technology could be highly efficient in solving food safety problems and may be applied to improve food quality with the potential to improve storage life. The potential applications of the BioLargo AOS filter in the food industry could be endless -- from primary commodities to finished food products."

She further explained, "At the foundation of the AOS Filter is its efficiency in generating a highly oxidative state. The data supports its potential to accomplish high-level disinfection that can be useful in multiple markets including food processing and agriculture production. Extremely high levels of performance [disinfection] were achieved during testing and we are excited to expand the work with BioLargo to other applications targeting food safety concerns."

The company intends to expand its focus to include commercial opportunities for its AOS Filter within the agriculture and food processing industry. Its commercial success will depend upon commercial scale testing, finalizing design and engineering, refining target markets and proving efficacy, as well as general business sales, distribution and/or licensing resources, and appropriate regulatory approvals where needed.

Dennis Calvert, President of BioLargo, stated: "This validation further demonstrates the effectiveness of our AOS Filter technology and it points to the growing excitement for our significant commercial opportunity across multiple industries. We have already demonstrated the AOS Filter's ability to dismantle organic molecules commonly trapped in water, in 'seconds vs. hours' and at extremely low power levels. It is believed to offer a low cost solution when compared to all other technologies. Now, by expanding the work to include high-level disinfection within the food and agriculture industry, we can confidently point to the expanded scope of our future commercial markets. We believe the AOS Filter will dramatically impact every segment of the $350 billion water industry. We believe that many market opportunities will include strategic alliances and joint venture partners to exploit such a large opportunity as ours. We look forward to sharing additional scientific results as the various researcher teams publish them. We are very excited about this milestone, the expanding work within the Department of Agricultural, Food and Nutritional Science at the University of Alberta, and the massive commercial future for our AOS Filter."
